What Are a 70-Inch LED TV’s Complete Dimensions?

Typically, a 70-inch LED TV is 61 inches tall and 34.25 inches broad. The advertised television size is determined by measuring the distance diagonally between the two corners of the TV; most HD televisions have a 16:9 aspect ratio.

The diagonal distance of a television is always greater than either its height or its breadth.

If both TVs have the same aspect ratio, a TV that is diagonally twice as big as a smaller TV has more than four times the total viewing area. A 50-inch TV’s size is almost double that of a 70-inch TV.
